Flex Power Modules announces the PKJ7200W, a series of EN50155-compliant DC/DC converter modules for railway rolling stock equipment.

Provided in a half-brick format, the PKJ7200W delivers up to 200 W output power, with an ultra-wide input voltage range of 14 V to 160 V.

Due to its wide input voltage range, the PKJ7200W can be used in railway applications anywhere in the world, where previously at least two product variants would be required. This makes installation, qualification and aftermarket support simpler – saving time and reducing costs.

The new module will comply with the EN50155 specifications for surge protection, power interruption and backup with external circuitry, wide operational temperature, and shock and vibration.

The module includes input under voltage protection, output over current protection, output over voltage protection, and over temperature protection. MTBF is 4 million hours.
